best mods so far...

don't think it does. you can just unplug it whenever you need any testing done. and plug it back in after. I live in California and was worried about CARB compliance, but it's not an issue.

Did I read on this forum somewhere where the Carbyte unit doesn't engage the fuel management delete function until you've reached 40 mph? (And then it's engaged for the remainder of the engine cycle...?) Is that true?

SO I've spent a lot of time and money on trying to make my 2023 Yukon Denali sound and perform its best.
I'm super picky about sound particularly and have tried 5 different mufflers from Magnaflow, Flowmaster and so forth.
I finally found the absoulte BEST muffler...BORLA Pro XS Universal Muffler (#40359)
Makes the truck SOUND how it's suppose to...nice deep rumble, NO DRONE and you really can't hear too much from the inside.
Sounds SO GOOD and I am so happy and wanted to share LOL.

For $115, it is easily the best mod for all of US without going full catback, which is WAY more expensive.

Also I researched Pedal Monster, Pedal Commander, RANGE DFM disabler, and I came across CARBYTE by OBD Solutions.
WOW what a REAL difference this makes. Full V8 MODE at all times, no coasting issues. Also disables the auto start/stop 100% of the time.
The power band of the truck feels much more linear and throttle response has improved. I'm sure I may lose some MPG but let's be honest, we don't have these vehicles to be "fuel friendly"

Just wanted to share my thoughts and experiences with these products! Cheers All~!

I immediately did several things. I permanently disabled engine Stop / Start. This will improve engine life, as well as safety. I also disconnected the daytime running lights. I can turn them on manually if I want to, but two government studies have shown NO safety benefit to driving with your lights on during the day. It improves the looks tremendously, my car no longer looks like a Christmas tree going down the road. I changed the circuitry to the cigarette lighter aka power port, so they are on all the time. Modified so that the vehicle will idle for more than 20 minutes and accessories can also stay on for more than 20 minutes (I need this for Drive-In movies). I consider everything I've done as correcting design mistakes in the vehicle.

No not true...from the research I have done and through my own experience it does not seem that way. I know the RANGE disabler had a coasting issue, the Carbyte does not, it's full V8 mode 100% of the time. They do have a solid return policy, i recommend trying it out for yourself!
